London mayor Boris Johnson officially marked the start of excavations for the Northern Line Extension (NLE) today with the start of the conveyor for the work.
Johnson visited the site to give the signal to start the 300m conveyor that will be used to transfer 600,000t of material to barges on the Thames.
Contracting joint venture Ferrovial Agroman Laing O’Rourke is undertaking construction of two new 3.2km tunnels and two new stations – one at Battersea Power station and another near the new US embassy – that are scheduled to open in 2020.
Work on diaphragm walls for the station box at Battersea Power Station is already being undertaken by Cementation Skanska but the actual tunnelling work is not scheduled to start until early 2017.
“The whirring into action of this fantastic machine marks a key moment in the delivery of the Northern line extension,” said Johnson. “This gigantic conveyor belt will enable a staggering 600,000t of material to be excavated from beneath south London and transported safely by barge on the Thames.
“Once built, the extension of the Northern line will act as a major spur to regeneration and growth in the area. It will open up the Tube to thousands more Londoners, cut journey times and act as a catalyst for the creation of much-needed new homes and jobs. It is one of a number of major ongoing investments we’re making into improving London’s transport infrastructure, which will be ever more important as our city continues to grow.”
Material excavated from the NLE work will be transported by barge to Tilbury in Essex where is will be used at nearby Goshems Farm to create arable farmland.
